delphi7下安装cooltrayicon的问题(100分)

[Warning] CoolTrayIcon_D7plus.dpk(3): File not found: 'CoolTrayIcon_D6plus.res'
[Fatal Error] CoolTrayIcon_D7plus.dpk(31): Required package 'rtl' not found


出现以上问题，我该怎么解决啊，谢谢热心人啊

你可以直接装他的.pas文件，给它一个新包

componet->install componet->into new package
unit file name:'CoolTrayIcon.pas
....
....

ok就行了，记得在library里面将path加进来。CoolTrayIcon我装了n遍了

还是不行啊，你用的是delphi 7吗？

{ For MinimizeToTray to work, we need to know when the form is minimized
(happens when either the application or the main form minimizes).
The straight-forward way is to make TCoolTrayIcon trap the
Application.OnMinimize event. However, if you also make use of this
event in the application, the OnMinimize code used by TCoolTrayIcon
is discarded.
The solution is to hook into the app.'s message handling (via HookApp).
You can then catch any message that goes through the app. and still
use the OnMinimize event. }

need for it. }

{ HandleIconMessage handles messages that go to the shell notification
window (tray icon) itself. Most messages are passed through WM_TRAYNOTIFY.
In these cases use lParam to get the actual message, eg. WM_MOUSEMOVE.

interpolates the OnClick event when the user clicks the left button, and
makes the menu (if any) popup on left and right mouse down events. }
